paraffin embedding

Paraffin embedding is a technique used in laboratories to prepare tissue samples for microscopic examination. First, the tissue is preserved with a fixative, then dehydrated through a series of alcohol solutions to remove water. It is then infiltrated with molten paraffin wax, which penetrates the tissue and solidifies, creating a firm block. This paraffin block provides support, allowing thin slices (sectioning) to be cut precisely for microscopic analysis. This process ensures that delicate biological structures are maintained and can be examined in detail, aiding in diagnosis and research.
